STEAM TRAP AND REGULATOR.

SPECIFICATION forming part of Letters Patent No. 403,162, dated May 14, 1889. Application filed January 1l, 1889. Serial No. 296,112. (No model.)

T0 a/ZZ wwnt it may concern:

Be it known that I, ADOLPH WEBER, of Detroit, in the county of Vayne and State of Michigan, have invented new and useful Improvements in Steam Traps and Regulators; and I hereby declare that the 'following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to that class of steam traps and regulators in which the opening of the valves for the passage of the steam and the water of condensation are governed by the expansion of a thermostatic tube or rod and regulated on the outside; and it consists in the means by which the expansion of a thermostatio tube or rod closes the valves of the steam-regulator and the trap for the water of condensation, and in the means for regulating the extent of the opening of said valves, and the combination and arrangement of the parts, as hereinafter more particularly set forth. By means of my invention the supply 'of steam is governed and regulated by the same means as the trap for the discharge of the water of condensation, so that the amount of steam in the pipes whencondensed will not be in excess of the discharge, and the opening of the valves through which the water is discharged will be so governed that it will be just sufficient for that purpose, so that there will be no backflow of the water in the pipes and the waste of steam prevented.

Figure l is a vertical section of my steam trap and regulator. Fig. 2 is a plan view, partially sectional, through the line :o a; in Fig. l. Fig. 3 is a sectional view of the cylinder in one piece, the ends integral with the cylinder, the central portion being broken out. Fig. 4 is a plan view of the same with the central portion broken out.

In the drawings, A represents a hollow iron cylinder, in which the thermostatic tube O is inclosed. This cylinder has on its upper side and near its outer end a nipple, a, into which is tapped a female screw-thread which receives the lower end of the main system of piping for heating purposes. On the lower side of the cylinder and near the other end is the nipple a, into which is tapped a screw thread, the pipe K connecting the cylinder to the wat-er or waste valve. The outer end of the cylinder is solid, being cored and internally screw-threaded to receive the inner end of the brass tube C. This cylinderA may be made in one piece with solid ends, one end beingcored and internally screw-threaded to receive the inner end of the brass tube C, and the other end cored for the passage of the tube O and for a stuffing-box on its outer face, the stuffing-box being internally screw-threaded for the reception of the gland F.. The wings b b and d d are cast integral with the cylinder, and are perforated for the passage of the rods F F.

B is a cap on the outer end of the cylinder A, cored and provided with the annular flange b', in which the end of the cylinder rests. Two wings b b project from the opposite sides of the cap B, and are perforated for the passage of the rods F F. The other end of the cylinder A is internally screw-threaded for the reternally screw-threaded and cored for the.

passage of the brass tube O.

B is a cap, which is connected with the cylinder A by the rods F F, and is cored for the passage of the brass tube O. The cap B is provided with wings b2 b2, which are perforated to allow the insertion of the rods F F.

Four studs, b3 b3 b4 b, project from an annular iiange on the outer face of the cap B and are arranged in pairs-one pair on the upper side and one pair on the lower side of the cap.

F F are rods passing through the wings on the cylinder or caps and the cap B', and are screw-threaded at the ends, upon which are screwed the nuts ff. These rods and nuts form the connection between the cylinder A and the cap B', and regulate the extent of the action of the thermostatic tube C. on the IOO ends ot the levers L L. This brass tube at its inner end is screwed into the cored outer end o' the cylinder A, and extends through the entire length of the cylinder and passes freely through the cap l), the stuiting-box d, the hollow gland E, and the cap B', and is closed at its outer end by the cap e, which is screwed into the tube, the other end being open to the air. A brass rod may be used in place oi the tube, it' desired.

L L are levers slightly curved on their inner and shorter arms, where they are in contact with the cap e on the brass tube C. These levers are pivoted at Z Z in the studs b3 Us D' D", projecting trom the cap l5. Their outer and longer arms are provided with the thumbscrews G G and nuts g y.

The end of the thiinibscrew G rests against the outer end of; the smooth valve-stem O oi` the valve ll, and actuates the same to close the valve. The valve ll is a valve ot the ordinary construction, having` a pipe leading' trom the boiler inserted in the inlet-oritiee 71, and the end oi the pipe of the main system of piping Ainserted in the exit-oriliee 7L. This valve is kept open by the spring under the valve-stem when not closed by the action of the lever L. The end of the thumb-screw l rests against the smooth valvefstem 0 ot" the valve l, and actuates the same in closing the valve.

The valve l a globe-valve ot' any ordinary construction, and is below the cylinder A, with which it is connected by the pipe K, and has an outlet-orifice, fz, into which is screwed a waste-pipe tor the passage of the water of condensation.

Steam being admitted from the boiler, passes through the valve llV into the main system of pipes. As these pipes are colder than the steam, the latter condcnses rapidly and the water 0i' condensation runs down through the cylinder A and out through the discharge or waste valve l'. The weight ot the water and the pressure ot the steam keep this wastevalve open until it is closed by the action of the thermostatic tube on the lever L and the thumb-screw A. The water of condensation, being at iirst nearly ot' the temperature of the pipes, does not atlect the thermostatic tube; but as the temperature of the pipes rises the water also becomes heated and heats the thermostatic tube, which begins to expand. As the tube expands, it. presses against the lever L and through the thumbscrew G closes completely or partially the valve ll', and cuts oit the steamssupply. The temperature of the pipes being nearly that oi' the steam, the quantity ot' the water of condensation diminishes and a large opening is not needed for its discharge. The expansion ot' the theromstatic tube, which operates on the valve ll through the lever L, also closes in the same manner and at the same time the waste-'valve l by its action on the lever L and thumb-screw l. Thus, when the steam is freely admitted to the pipes and the amount oi condensation is large, themoriiice for the discharge of the water is sul'licient to allowr it all to tlow ott'. the temperature of the pipes increases, the amount of steam is decreased, the condensation is lessened, andthe oriticetor the discharge or waste proportionally diminished. rlhe expansion of the iron cylinder causes the pipe K and the valve I to move toward the outer end of the lever L, and thus assists in closing this valve. ly this construction and connection ot' the steam trap and regulator I am enabled to take advantage of the expansion of both the brass tube and oi' the iron cylinder, thus using' the total expansion ot' the two and not the d il'terential expansion in closing this valve l.

Ey means of the thumlrserews the extent oi' the opening oi' the valves can be easily changed when 'necessary and the supply olf steam regulated.
